The development of a country is dependent on the per person energy consumption rate, which is very low in Bangladesh. Bangladesh installed a capacity of 10416 MW electricity on June 2014 and three fourth of which is considered to be accessible. Near about 45% people has no access to electricity. Therefore, electricity shortage is an acute crisis in Bangladesh. As Saint Martin Island is far away from the main land, it is almost impossible and cost ineffective to supply electricity from the national grid. For connection of nearly 6000 peoples of Saint Martin to the main stream of development and to make this island more attractive to the tourists, it is very essential to provide electricity for them. Power generation by combining solar, wind and diesel, known as hybrid system can be the most efficient technique for the electrification of these types of Island. Based on this principle, in this paper a hybrid system is designed for electrification of Saint Martin’s Island. In the analysis, realistic data is used for load calculation and optimization analysis for most effective solution. Hybrid Optimization Model for Electric Renewable (HOMER) software is used to find out the final optimization and sensitive analysis of hybrid system. This system satisfies the load demand and reduces carbon emission which will help to generate green energy.
